qRT-PCR analysis of CEACAM5, KLK6, SLC35D3, MUC2 and POSTN in colon cancer lymph nodes-An improved method for assessment of tumor stage and prognosis.

One fourth of colorectal cancer patients having curative surgery will relapse of which the majority will die. Lymph node (LN) metastasis is the single most important prognostic factor and a key factor when deciding on postoperative treatment. Presently, LN metastases are identified by histopathological examination, a subjective method analyzing only a small LN volume and giving no information on tumor aggressiveness.

Extent of lymphadenectomy has no impact on postoperative complications after gastric cancer surgery in Sweden.

Objective: Curative gastric cancer surgery entails removal of the primary tumor with adequate margins including regional lymph nodes. European randomized controlled trials with recruitment in the 1990's reported increased morbidity and mortality for D2 compared to D1. Here, we examined the extent of lymphadenectomy during gastric cancer surgery and the associated risk for postoperative complications and mortality using the strengths of a population-based study.

Postoperative pancreatic fistula formation according to ISGPF criteria after D2 gastrectomy in Western patients.

Background: Limited information is available on the incidence of postoperative pancreatic fistula (POPF) after D2 gastrectomy with the strict use of the International Study Group of Pancreatic Fistula (ISGPF) criteria, particularly so in Western patients.

Methods: All patients who underwent gastrectomy for adenocarcinoma at the Karolinska University Hospital Huddinge from 2006 until June 2012 were identified via hospital records and reviewed for type of surgical procedure, postoperative morbidity, incidence, and risk factors for POPF.

Results: Ninety-two of 107 cases had a D2 gastrectomy eligible for evaluation of POPF, of which 83 (90 %) also underwent bursectomy.
